No there no were specifically stated that Satan is a f****** power class. The author of dxd was a f****** useless when is came to writing about power systems and politics He was mostly interested in writing comedy and Harem. What was the main character of the dxds power yes it was boost and Dragon aura. First one help the author to fight above the main characters abilities. Second allowed the author justify why girls like him. And last and finally if satan class exist as a power rank then why was razvim was never referred above or same level as the others.
ThatsClassified:This class was the highest class a Devil could attain by either training or being born with great power (until the creation of the Special-class Devil rank). As a devil comes into this class, they gain a rank in the Underworld as Satan, Great King, King, Archduke, Archduchess, Duke, Duchess, Prince, or Princess, Satan class is indeed a class, the great Satan's and maous in Japanese translation are different from the "Satan class" and the position
I belive the Satan class level is above ultimate but before super because sercies was a super devil when he went against the other Satan class devils in the Civil War, and they were confirmed by the story to stronger than ultimate but weaker than them so it's a small/large strength gap between ultimate - Satan and super devils
